Calivr, The Leviathan

One of the Ancient Ones of The Deep. While having many names, Calivr is known by many simply as The Leviathan and is infamously the most powerful Ancient One known to Nevalia. While not widely known, most of Calivr's power comes from two sources: a deal made between him and the young giant, Karn, and the siphoning of dreams from the dragon, Qrorra. The result of this power led to his massive size. While having spent thousands of years with a portion of his blood and power being granted to Karn, recently their bond was severed granting them both freedom.

Calivr swims in The Deep just below where The Platinum City was built. There's an entire ecosystem that exists upon Calivr's back known as Calivr's Plane.
